Amazon Prime Day features significant discounts you won't see again until later this year. Amazon Prime Day kicks off from July 16 to 17, and for 48 hours, Amazon Prime members will have access to special offers across a wide selection of products. We've rounded up some of the biggest discounts, up to 52% off the list price, you can find during the two days. You can find big savings and some of the best prices on vacuums, headphones, bedding and kitchenware. Many of these products will be available for Amazon Prime members at record-low prices.

Amazon Prime Day covers deals across every department -- but at Engadget, we focus on discounts that apply to the tech we've tested and recommend. Not surprisingly, much of that gear can be pretty pricey. Cables, chargers, mini speakers and budget earbuds might not be as flashy as a laptop or a new TV, but they're arguably just as important. Also, it feels good to snag some small stuff for 40, 30 and even 20. Check out the list below for a few dozen of the best Prime Day tech deals under 50. As with all Engadget tech deals coverage, we only highlight discounts on gear we've tested or have otherwise used and know to be worthy of your money. We cross-checked our guides and reviews with the Prime Day deals Amazon has put forth to come up with what you see here. The smallest Echo speaker is the Echo Pop, and right now it's down to 18 instead of the full 40, which is a 55 percent discount and matches the lowest price we've seen from past sales.

I have a perhaps inappropriate, anthropomorphic relationship with whatever robot vacuum is running in my house. No matter how much trouble they cause me--if they get trapped in the ledge by the fireplace or lost under the couch--I never forget that it's here to help me battle the chaotic mess that my two kids and two dogs perpetrate upon me daily. Have I convinced you that you need one, too? You're in luck because the Amazon Prime Day vacuum deals lineup includes five of my top picks. Whether you need an all-in-one cleaning station, a simple picker-upper after dinner, or one with an air freshener, we have you covered.

WIRED's coverage of the best Amazon Prime Day deals is, as they say, built different. For starters, we only include products someone from our team has personally tested and reviewed. That means you will not find any flimsy fad gadgets or shoddy dupes among our recommendations. What remains is all solid stuff. You'll often find a link to a longer write-up to a review or buying guide if you want to make a fully informed buying decision. Additionally, we obsessively track prices to make sure everything on the list is a genuinely good price right now. For more on that, consult our helpful guide to shopping like a pro on Prime Day. We test products year-round and handpicked these Prime Day deals. Products that are sold out or no longer discounted will be crossed out. We'll update this guide regularly throughout Prime Day by adding fresh deals and removing dead deals. Logitech makes a lot of great, functional keyboards, but the Pop Keys (9/10, WIRED Recommends) not only leverage the ...

While you can often find discounts on Echo speakers, Fire tablets, Kindles and other Amazon devices throughout the year, Amazon Prime Day is the best time to buy them, period. The online retailer usually discounts most of its own hardware for its special, members-only shopping event in the summer, and those discounted prices are typically only rivaled by Black Friday sales. In recent years, Prime Day discounts on these gadgets have even been better than those we've seen during the holiday shopping season. For Amazon Prime Day 2024, you'll find most of Amazon's devices on sale for record-low prices (or close to them). These are the best Prime Day deals you can get on Kindles, Fire TVs, Echos and more.

Amazon Prime Day is a chance for Prime members to pick up all sorts of things on sale, and while most of the discounts aren't worth your time, those on gadgets actually can be. Prime Day deals have discounted plenty of our favorites in the past, and this year is shaping up to be no different. If any of the items on your list happen to be tech or tech related, Engadget has you covered. We've scoured Amazon to find the Prime Day deals on tech and gadgets that you can get this year. And the good news is that not all of the discounts are on high-priced items.

We propose a method that can generate customer trajectories and purchasing behaviors in retail stores simultaneously using Transformer-based deep learning structure. Utilizing customer trajectory data, layout diagrams, and retail scanner data obtained from a retail store, we trained a GPT-2 architecture from scratch to generate indoor trajectories and purchase actions. Additionally, we explored the effectiveness of fine-tuning the pre-trained model with data from another store. Results demonstrate that our method reproduces in-store trajectories and purchase behaviors more accurately than LSTM and SVM models, with fine-tuning significantly reducing the required training data.

In this paper, we consider a multi-stage dynamic assortment optimization problem with multi-nomial choice modeling (MNL) under resource knapsack constraints. Given the current resource inventory levels, the retailer makes an assortment decision at each period, and the goal of the retailer is to maximize the total profit from purchases. With the exact optimal dynamic assortment solution being computationally intractable, a practical strategy is to adopt the re-solving technique that periodically re-optimizes deterministic linear programs (LP) arising from fluid approximation. However, the fractional structure of MNL makes the fluid approximation in assortment optimization highly non-linear, which brings new technical challenges. To address this challenge, we propose a new epoch-based re-solving algorithm that effectively transforms the denominator of the objective into the constraint. Theoretically, we prove that the regret (i.e., the gap between the resolving policy and the optimal objective of the fluid approximation) scales logarithmically with the length of time horizon and resource capacities.

We propose a transformer architecture for time series forecasting with a focus on time series tokenisation and apply it to a real-world prediction problem from the pricing domain. Our architecture aims to learn effective representations at many scales across all available data simultaneously. The model contains a number of novel modules: a differentiated form of time series patching which employs multiple resolutions, a multiple-resolution module for time-varying known variables, a mixer-based module for capturing cross-series information, and a novel output head with favourable scaling to account for the increased number of tokens. We present an application of this model to a real world prediction problem faced by the markdown team at a very large retailer. On the experiments conducted our model outperforms in-house models and the selected existing deep learning architectures.

If you've been looking to improve your home's security but don't want to spend a fortune, Amazon Prime Day presents an excellent time to shop for some new gear. For 120 -- down from 320 -- you can get a Blink Video Doorbell and three Outdoor 4 smart security cameras with Sync Module 2. Like most Prime Day deals, this one is exclusive to Prime members in the lead-up to the big day. The bundle is currently 63 percent off. The Blink bundle allows you to monitor your home, whether you're far away or right inside. You can use Video Doorbell to answer the door, get alerts when there's motion and speak to visitors. It uses infrared night vision and 1080p HD live view to give you insight during the day or night.
